A hydraulic control system for vehicle includes: an engine; an oil pump driven by the engine; a clutch device brought into engagement to enable power transmission between the engine and drive wheels by delivering a pressurized fluid thereto, and brought into disengagement to interrupt the power transmission between the engine and the drive wheels by discharging the fluid therefrom; and an accumulator storing the fluid delivered to the clutch device. The hydraulic control system is configured to control the hydraulic pressure applied to the clutch device, to stop the engine while bringing the clutch device into disengagement upon satisfaction of a predetermined stopping condition, and to restart the engine while bringing the clutch device into engagement upon satisfaction of a predetermined restarting condition. In the hydraulic control system, a hydraulic circuit increases flow rate of the fluid flowing between the accumulator and the clutch device when the engine is stopped.
